Split billing for a user across multiple billing systems

ABSTRACT

The disclosed system provides a facility for split billing for a single user on multiple billing systems. The disclosed system activates the user on each respective billing system using a unique pairing, such as an international mobile subscriber identity that identifies the user, and a mobile station international subscriber directory number that identifies a particular user device. As device data is routed through a telecommunication network via each access point name (APN), the network generates call detail records (CDRs), which include an indication of the APN used. The CDRs are routed to a mediations platform that uses the received APN information to route each CDR to the appropriate target billing system. For example, CDRs identifying a APN may be routed to a telematics billing system, which then generates a bill that is sent to a car dealership.

This application is a continuation of U.S. patent application Ser. No. 16/058,956, filed on Aug. 8, 2018, and entitled “SPLIT BILLING FOR A USER ACROSS MULTIPLE BILLING SYSTEMS,” the disclosure of which is hereby incorporated herein in its entirety by reference.

BACKGROUND

In a typical telecommunications billing system, a user is activated on a single billing system where taxation, invoicing, and retail billing functions are performed and maintained. However, as embedded subscriber identity module (eSIM) and Internet of Things (IoT) technologies become more widespread, scenarios arise in which a single billing system is unable to adequately meet the needs of telecommunications service providers and end users. For example, a scenario in which a single user purchases a car having telematics capabilities (e.g., navigation or real-time monitoring of driver behavior) and infotainment capabilities (e.g., streaming multimedia such as movies or music to an electronic device installed inside of the car) could raise such concerns. This is particularly true if the telematics usage is charged under a first rate plan (e.g., a flat monthly fee) that is billed directly to a first party such as a car dealership or a car manufacturer, while the infotainment usage is charged under a second rate plan (e.g., a per-gigabyte fee) that is billed directly to a second party such as the user herself. Under traditional billing systems, a single bill would be generated and sent to only one party (e.g., the car dealership or the user), causing the party receiving the bill to manually coordinate payment with one or more other financially responsible parties. These and other problems exist with traditional billing systems. Therefore, a need exists to provide split billing for a user across multiple billing systems such that two or more individual parties may be billed separately for telecommunications services associated with a single user having multiple electronic devices.

DETAILED DESCRIPTION

A system for split billing for a single user on multiple billing systems is disclosed. For example, the disclosed system would enable a user's connected car to be associated with two billing systems: a first billing system that bills a car dealership (or other entity) for data used by a telematics device in the car; and a second billing system that bills the user herself for data used by an infotainment device in the car. Users are activated on a billing system which rates usage based on a rate-plan (e.g. 100 MB data for $4.99) with a unique pair being associated with each activated user. As described herein, the disclosed system extends the concept of user activation on a single billing system to activation across multiple billing systems such that differentiated or split billing can be achieved. The disclosed system activates the user on each respective billing system using a unique pairing, such as an international mobile subscriber identity (IMSI) and mobile station international subscriber directory number (MSISDN) pair. For example, the user may be activated using an IMSI-1/MSISDN-1 pair for a telematics billing system and an IMSI-1/MSISDN-2 pair for an infotainment billing system.

Each respective user device is configured to route data through a telecommunications network using a predetermined access point name (APN). An APN may correspond to a gateway connecting two networks (e.g., a 5G network and the public Internet) that was used to transmit or receive information from a respective user device 105 a-105 n (FIG. 1). For example, a telematics device may route data via APN-1 and an infotainment device may route data via APN-2. As user device data is routed via each APN, the network generates call detail records (CDRs) that each include an indication of the APN used. The CDRs are routed to a mediations platform that uses the received APN information to route each CDR to the appropriate billing system. For example, CDRs identifying APN-1 may be routed to a telematics billing system, which then generates a bill that is sent to a car dealership. Similarly, CDRs identifying APN-2 may be routed to an infotainment billing system, which then generates a bill that is sent directly to the user. Overall, the disclosed system allows different types of usage from the same device to be billed on two different billing systems for two potentially different entities.

Various embodiments of the invention will now be described. The following description provides specific details for a thorough understanding and an enabling description of these embodiments. One skilled in the art will understand, however, that the invention may be practiced without many of these details. Additionally, some well-known structures or functions may not be shown or described in detail, so as to avoid unnecessarily obscuring the relevant description of the various embodiments. The terminology used in the description presented below is intended to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments of the invention.

FIG. 1 is a diagram of a representative environment 100 in which a system to provide split billing for a user across multiple billing systems may operate. Although not required, aspects and implementations of the system will be described in the general context of computer-executable instructions, such as routines executed by a general-purpose computer, a personal computer, a server, or other computing system. The system can also be embodied in a special purpose computer or data processor that is specifically programmed, configured, or constructed to perform one or more of the computer-executable instructions explained in detail herein. Indeed, the terms “computer” and “computing device,” as used generally herein, refer to devices that have a processor and non-transitory memory, like any of the above devices, as well as any data processor or any device capable of communicating with a network. Data processors include programmable general-purpose or special-purpose microprocessors, programmable controllers, application-specific integrated circuits (ASICs), programmable logic devices (PLDs), or the like, or a combination of such devices. Computer-executable instructions may be stored in memory, such as random access memory (RAM), read-only memory (ROM), flash memory, or the like, or a combination of such components. Computer-executable instructions may also be stored in one or more storage devices, such as magnetic or optical-based disks, flash memory devices, or any other type of non-volatile storage medium or non-transitory medium for data. Computer-executable instructions may include one or more program modules, which include routines, programs, objects, components, data structures, and so on that perform particular tasks or implement particular abstract data types.

In the environment 100, user devices 105 a-105 n are associated with a single user, which may be a person or an entity who is a subscriber to services provided by a telecommunications service provider. Each of user devices 105 a-105 n may be any electronic device capable of sending or receiving data via network 110, as discussed in more detail below with respect to FIG. 2. Network 110 may be any network, including a telecommunications network, capable of facilitating the transfer of data between user devices 105 a-105 n, network 110, and one or more external application servers, websites, and/or computer systems (not shown). In one embodiment, network 110 may be an Internet Protocol Multimedia Subsystem (IMS) network. IMS is an architectural framework for delivering Internet Protocol (“IP”) multimedia to mobile users, such as users of mobile devices like smart phones or tablet computers. An IMS core network (“IMS core”) permits wireless and wireline devices to access multimedia, messaging, and voice applications and services. IMS standards and specifications have been promulgated by the 3rd Generation Partnership Project (“3GPP”™). To allow the IMS core to be integrated with Internet resources, the 3GPP specifications use Internet Engineering Task Force protocols within the IMS core, such as Session Initiation Protocol (“SIP”) and Diameter. SIP is a signaling protocol used for creating, modifying and terminating two-party or multiparty sessions consisting of one or several media streams.

FIG. 2 is a representative block diagram 200 of a user device 105 a-105 n in accordance with embodiments herein. Each user device 105 a-105 n may include a processor 230 for executing processing instructions, a data storage medium component 240 (e.g., hard drive, flash memory, memory card, etc.), volatile memory and/or nonvolatile memory 250, a power supply 270, one or more network interfaces (e.g., Bluetooth Interface 210; and Network Communication Interface 215, which enables the user device to communicate by transmitting and receiving wireless signals using licensed, semi-licensed or unlicensed spectrum over a telecommunications network), an audio interface 245, a display 220, a keypad or keyboard 225, a microphone 235, one or more sensors 260 (e.g., accelerometers, speedometers, engine diagnostic sensors, etc.) that are used to facilitate particular functions of the electronic device, and other input and/or output interfaces 255. The various components of the user devices may be interconnected via one or more buses. The volatile and nonvolatile memories generally include storage media for storing information such as processor-readable instructions, data structures, program modules, or other data. Some examples of information that may be stored include basic input/output systems (BIOS), operating systems, and applications. The stored information may include one or more Session Initiation Protocol (SIP) or Diameter protocol clients capable of generating, transmitting and interpreting syntactically correct SIP or Diameter protocol messages. SIP clients permit the mobile device to register with and communicate via networks such as IMS networks.

Each user device 105 a-105 n may be virtually any device for communicating over a wireless network. Such devices include application servers or mobile telephones, such as Global System for Mobile Communications (“GSM”) telephones, Time Division Multiple Access (“TDMA”) telephones, Universal Mobile Telecommunications System (“UMTS”) telephones, Evolution-Data Optimized (“EVDO”) telephones, Long Term Evolution (“LTE”) telephones, Generic Access Network (“GAN”) telephones, Unlicensed Mobile Access (“UMA”) telephones, and other mobile computers or devices, such as Voice over Internet Protocol (“VoIP”) devices, Secure User Plane Location (“SUPL”) Enabled Terminals (SETs), Personal Digital Assistants (“PDAs”), radio frequency devices, infrared devices, handheld computers, laptop computers, wearable computers, tablet computers, pagers, infotainment systems, vehicle-mounted devices, Internet of Things (IoT) devices, and integrated devices combining one or more of the preceding devices, and/or the like.

Each user device 105 a-105 n may connect to a telecommunications network via a trusted radio access network (RAN) or an untrusted RAN. A single user device may be capable of using one or both types of RANs. The RANs may use any wireless communications and data protocol or standard, such as GSM, TDMA, UMTS, EVDO, LTE, GAN, UMA, Code Division Multiple Access (“CDMA”) protocols (including IS-95, IS-2000, and IS-856 protocols), Advanced LTE or LTE+, Orthogonal Frequency Division Multiple Access (“OFDM”), General Packet Radio Service (“GPRS”), Enhanced Data GSM Environment (“EDGE”), Advanced Mobile Phone System (“AMPS”), WiMAX protocols (including IEEE 802.16e-2005 and IEEE 802.16m protocols), Wireless Fidelity (“WiFi”), High Speed Packet Access (“HSPA”), (including High Speed Downlink Packet Access (“HSDPA”) and High Speed Uplink Packet Access (“HSUPA”)), Ultra Mobile Broadband (“UMB”), SUPL, and/or the like.

Returning to FIG. 1, as user devices 105 a-105 n transmit and receive data via network 110, call detail records (CDRs) 115-117 are generated to enable the telecommunications system to track usage of each user device for billing purposes. A CDR is a data record that is produced by a component in a telecommunications network to capture details of transmissions to or from a user device on the network. A CDR may contain multiple attributes associated with the transmissions, such as time, duration, completion status, source number, destination number, sequence number, transmission type (e.g., telephone call, SMS message, MMS message, etc.), error or fault conditions, an associated user or subscriber identification, and/or routing information. In the disclosed system, example CDRs 115-117 are received by mediations platform 120 and processed as described herein.

The particular routing information contained in CDRs 115-117 may comprise Access Point Name (APN) information. As explained in more detail herein, the disclosed system may use APN information to help determine the particular billing system 125 a-125 c to which each received CDR should be routed. The source number information contained in each received CDR may comprise a mobile station international subscriber directory number (MSISDN) that is sufficient to uniquely identify a particular user device (e.g., user device 105 a or user device 105 b, etc.) associated with a data transmission. In addition, the associated user or subscriber information contained in each received CDR 115-117 may comprise an international mobile subscriber identity (IMSI) that is sufficient to uniquely identify a user who is associated with one or more respective user devices 105 a-105 n.

Mediations platform 120 receives each CDR 115-117 and determines which particular billing system 125 a-125 c is associated with each received CDR. On each billing system, the user is activated using a unique identification pairing so that each respective billing system can separately track and bill usage across multiple user devices 105 a-105 n that belong to the user. The unique identification pairing on each billing system may correspond to an IMSI/MSISDN pair that identifies the user and the user's respective device. The IMSI for a particular user may stay consistent across all of the multiple billing systems. By contrast, the MSISDN may be unique for each separate user device 105 a-105 n. For example, User A may own an automobile that contains two user devices: a telematics device 105 a and an infotainment device 105 b. A first billing system 125 a may be responsible for generating bills for telematics usage. Therefore, User A has a primary activation on the first billing system 125 a using an IMSI-1/MSISDN-1 pair, where IMSI-1 uniquely identifies User A while MSISDN-1 uniquely identifies telematics device 105 a. In some embodiments, particularly embodiments in which the user device includes a SIM with a single profile, network usage will occur only with the IMSI-1/MSISDN-1 pair. Continuing the example, a second billing system 125 b may be responsible for generating bills for infotainment usage (e.g. streaming music/audio/video service usage). Therefore, User A has a secondary activation on the second billing system 125 b using an IMSI-1/MSISDN-2 pair, where IMSI-1 uniquely identifies User A while MSISDN-2 uniquely identifies infotainment device 105 b. Subsequently, when each respective billing system receives a CDR from mediations platform 120, the billing system may read IMSI/MSISDN information from the CDR in order to track device usage, generate a bill, and send it to the appropriate user or party. In some embodiments, the MSISDN information used for a primary activation on a billing system may be transmitted to the corresponding user device, while in other embodiments the MSISDN information used for the primary activation may not be transmitted to the corresponding user device. In some embodiments, the MSISDN information for a secondary activation on a billing system may not be transmitted to the corresponding user device.

Mediations platform 120 is responsible for receiving a CDR, determining the specific billing system that should process the received CDR for billing purposes (i.e., the target billing system), modifying the received CDR if necessary in order to conform with a prior activation on the target billing system, and transmitting the CDR to the target billing system for processing. Mediations platform 120 uses a series of rules to determine how a received CDR should be processed and transmitted to a target billing system. To process received CDRs, mediations platform 120 may maintain one or more mediations tables that contain information necessary to route each received CDR to the appropriate respective billing system.

Various alternative embodiments are possible with the disclosed system, including embodiments wherein a first party is billed for usage associated with a first telematics device and a first infotainment device (per sample entries 325 a and 325 b, as explained below with reference to FIG. 3A), and embodiments wherein a second party is billed for usage associated with a second telematics device and a second infotainment device (per sample entries 325 c and 325 d, as explained below with reference to FIG. 3A). Still other various alternative embodiments are possible with the disclosed system.

FIG. 3A depicts a first example mediations table 300 that facilitates split billing in accordance with embodiments herein. Each sample entry 325 a-325 d in mediations table 300 corresponds to a rule for determining how mediations platform 120 routes each received CDR to the appropriate target billing system. Mediations table 300 includes “Subscriber” column 305, “Route” column 310, “Target Billing System” column 315, and “Target Device ID” column 320. For each sample entry 325 a-325 d in mediations table 300, Subscriber column 305 contains an identifier that uniquely identifies a single user or telecommunications subscriber (e.g., User A). In an embodiment, the identifier contained in Subscriber column 305 comprises an IMSI of the associated user or telecommunications subscriber. In an embodiment, mediations platform 120 reads the IMSI from a received CDR and stores the IMSI in Subscriber column 305.

For each sample entry 325 a-325 d in mediations table 300, Route column 310 contains an identifier that uniquely identifies a route through which data passes in a telecommunications network. In an embodiment, mediations platform 120 reads the route data from a received CDR and stores the route data in route column 310. The route data stored in column 310 may comprise an identification of an APN that was used to route user device data through the telecommunications network. Each entry in Target Billing System column 315 contains an identifier that uniquely identifies a billing system to which a received CDR should be routed based on information contained in mediations table 300, as described in more detail below. Target Device ID column 320 contains an identifier that is unique to the user device that is associated with the received CDR. The identifier stored in Target Device ID column 320 is also the identifier initially used to activate the user device on the associated target billing system. Therefore, mediations platform 120 may alter the Target Device ID in the CDR before transmission to a target billing system to ensure that the Target Device ID is consistent with a previous activation on the target billing system.

Mediations table 300 includes sample entries 325 a-325 d which correspond to four sample rules that may be enforced by mediations platform 120 to determine the target billing system for a received CDR. According to sample entry 325 a, when mediations platform 120 receives a CDR having a subscriber value of IMSI-1 (indicating, e.g., User A) and a Route value of APN-1 (indicating, e.g., telematics usage), then mediations platform 120 will transmit the received CDR to Billing System 1 (i.e., the desired or proper target billing system), where the CDR includes a subscriber value of IMSI-1 and a target device ID of MSISDN-1. As explained herein, Billing System 1 uses the IMSI-1/MSISDN-1 pair in the CDR received from mediations platform 120 to facilitate generating a bill for User A (corresponding to IMSI-1) for data usage of the user device corresponding to MSISDN-1 (e.g., a first telematics device).

According to sample entry 325 b, when mediations platform 120 receives a CDR having a subscriber value of IMSI-1 (again indicating User A) and a Route value of APN-2 (indicating, e.g., infotainment usage), then mediations platform 120 will transmit the received CDR to Billing System 2 with a subscriber value of IMSI-1 and a Target Device ID of MSISDN-2. Mediations platform 120 transmits the CDR with the Target Device ID indicated in Target Device ID column 320, regardless of any device identification information present in the CDR as initially received. Billing System 2 uses the IMSI-1/MSISDN-2 pair in the CDR received from mediations platform 120 to facilitate generating a bill for User A (corresponding to IMSI-1) for data usage of the user device corresponding to MSISDN-2 (e.g., a first infotainment device).

According to sample entry 325 c, when mediations platform 120 receives a CDR having a subscriber value of IMSI-2 (indicating, e.g., User B) and a Route value of APN-1, then mediations platform 120 will transmit the received CDR to Billing System 1 with a subscriber value of IMSI-2 and a target device ID of MSISDN-3. As explained herein, Billing System 1 uses the IMSI-2/MSISDN-3 pair in the CDR received from mediations platform 120 to facilitate generating a bill for User B (corresponding to IMSI-2) for data usage of the user device corresponding to MSISDN-3 (e.g., a second telematics device).

According to sample entry 325 d, when mediations platform 120 receives a CDR having a subscriber value of IMSI-2 (again indicating User B) and a Route value of APN-2, then mediations platform 120 will transmit the received CDR to Billing System 2 (i.e., the target billing system) with a subscriber value of IMSI-2 and a Target Device ID of MSISDN-4. Mediations platform 120 transmits the CDR with the Target Device ID indicated in Target Device ID column 320, regardless of any device identification information present in the CDR as initially received. Billing System 2 uses the IMSI-2/MSISDN-4 pair in the CDR received from mediations platform 120 to facilitate generating a bill for User B (corresponding to IMSI-2) for data usage of the user device corresponding to MSISDN-4 (e.g., a second infotainment device).

FIG. 4 is a flowchart 400 showing a procedure for facilitating split billing for a user across multiple billing systems in accordance with embodiments herein. At block 405, a user is activated on a first billing system using a unique user identification (e.g., IMSI-1) and a unique user device identification for a first user device (e.g., MSISDN-1). At block 410, the same user is activated on a second billing system using the same unique user identification (e.g., IMSI-1) and a unique user device identification for a second user device (e.g., MSISDN-2). Although flowchart 400 only shows billing system activations at blocks 405 and 410, the disclosed system may complete any number of additional activations on additional, separate billing systems, and at different times. Each respective billing system on which the user is activated may bill for data usage under a different rate plan, and may generate and send bills or invoices to different parties for payment.

At block 415, mediations platform 120 receives a CDR associated with data usage from a user device and proceeds to block 420 to determine a target billing system associated with the received CDR. As explained herein, mediations platform 120 determines the target billing system for a received CDR based on information contained in the CDR and one or more rules maintained by mediations platform 120 in a mediations table 300. At block 425, the disclosed system transmits the received CDR to the target billing system in accordance with the rules maintained by mediations platform 120. As explained herein, the CDR that is transmitted to the target billing system contains at least a subscriber identifier (e.g., an IMSI) and a device identifier (e.g., a MSISDN) corresponding to a previous activation on the target billing system.

The disclosed system repeats blocks 415 through 425 for each CDR that is received as user devices consume data on a telecommunications network. At periodic intervals (such as at the end of a monthly billing cycle), each respective billing system generates a bill for the user based on the CDRs received by the respective billing system. Each respective billing system then sends the generated bills to the responsible financial party, which may be the user herself or a different party that is responsible for payment.
